The following ordering specification chart is provided for assistance in determining model number. Other options are possible, consult Danfoss with further questions. MCH X X X X X XXX Mounting option Control knob type Handle actuation Electrical characteristics Connector Factory assigned Mounting option Code Description Detail 1 Base (surface) mount aluminum case Four screws connect to the flanges on the bottom of the metal case. 2 Top mount (drop in) with plastic case Two screws connect to an enlarged mounting plate. Top mounting allows the entire handle to be removed from above the panel. The case is made of black nylon plastic. 3 Top mount (drop in) without case Two screws connect to an enlarged mounting plate. Top mounting allows the entire handle to be removed from above the panel. 4 Panel mount with plastic case Four screws connect to the top plate that holds the boot in place. The case is made of black nylon plastic. 5 Panel mount without case Four screws connect to the top plate that holds the boot in place. Control knob option Code Description Detail 1 Non-locking The friction-held handle detents with a springloaded ball to indicate null, while the spring-return handle has a spring preload indicating null.the non-locking handle has a standard ball knob. 2 Center lock The non-locking handle has a standard ballthe center lock handle has a cylindrical knob and provides a positive center lock that unlatches when the operator pulls up on the knob. 3 Non-locking, auxiliary push button switch This knob is teardrop shaped, with an auxiliary momentary push-button switch on top. The switch is wired through the handle shaft to the body with three wires (common, normally open, and normally closed). 5 Non-locking, no knob The customer provides customized knob. 6 Three position maintained rocker switch The cylindrical knob has a boot covering the three-position switch in the knob. The switch, wired through the handle, is used for auxiliary functions. 8 * Special (no handle or knob) 9 Three position momentary rocker switch This is the same as option 6, but the switch returns to the center position when released. * Unique configuration, for details contact your Danfoss representative. Handle actuation option Reference Dimensions. Code Description Detail A Spring return, bi-directional This handle uses a torsion spring to return to the mechanical center position and has 30 degrees of handle throw on either side of center. B Friction held, bi-directional This handle has an adjustable drag, set with a clamp-type brake that holds the handle at the set position and has 30 degrees of handle throw on either side of the center detent. Danfoss February BC en-US0601 5

6 Ordering information Handle actuation option (continued) Code Description Detail C Friction held, uni-directional This handle has 60 degrees of high-resolution of handle throw, rotating on only one side of mechanical null, which is at full stroke. It has no detent mechanism. D Special (friction held, center detent only, no brake) Electrical characteristics option Code Description Detail A Proportional, no switches, 12 VDC This handle s output curve is fairly linear, with output voltage as a function of handle stroke. The supply voltage is 12 Volts, and there are no auxiliary function switches. B Proportional, center off switch, 12 VDC, This handle has a center-off switch that ensures zero output voltage within ±3 degrees of handle center position. C Proportional, center off switch, 24 VDC Same as option B except this handle runs on a supply voltage of 24 Volts. D Proportional, center off and auxiliary switch, 12 VDC Same as option B except this handle has a second switch that actuates at +2 or -2 degrees. E Proportional, set-point potentiometer, 12 VDC Same as option B except this handle maintains the same polarity of signal in forward or reverse. F Step-plus-proportional, 12 VDC This handle uses two switches to give the step-plus-proportional output current on either side of null. This overcomes deadbands in spool valves (see Specifications on page 8, Step- Plus-Proportional-Control-Handle PWM option illustration). Current beyond this step output is proportional through the rest of the handle throw. Full current output at 30 degrees handle stroke is maximum of 250 ma. Step current is a maximum of 50% of full current output. G Step-plus-proportional, 24 VDC Same as option F, except this handle runs on a supply voltage of 24 Vdc. H Switching This handle is non-proportional. Moving the handle off null activates switches that power ON/OFF devices (for example, solenoid valves). J Step-plus-proportional, full auxiliary switching, 12 VDC This handle uses the step switches for additional secondary functions. Full current output at 30 degrees handle stroke is a maximum of 250 ma. Step current is a maximum of 50% of full current output. K Proportional, unwired switch The customer uses the unwired center switch to operate an auxiliary function, such as neutral start interlock. L * Electronic PWM auxiliary switching, 12 Vdc This handle uses a printed circuit board that makes the step height and output current fully adjustable, accommodating high current applications. It also has pulse width modulation, that dithers the output to overcome hydraulic valve stiction. Full current output at 30 degrees handle stroke is a maximum of 2 Amps into a 5 Ohm load. Step current is a maximum 50% of full current output. Typical dither frequencies (dependent on resistance of the load, specified in the suffix number) are: 60 Hz for the HPI solenoid actuator, approximately 400 Hz for the V7058 Hydrotransmission Valve and approximately 1000 Hz for the MCV101A/ MCV116A Pressure Control Pilot Valve. M Proportional, three switches The three switches are: a wired center switch; one unwired switch in forward; and one unwired switch in reverse. X Y Z Special (no handle or knob) Special Special * Option L, Electronic PWM auxiliary switching, 12 Vdc reached its end of life cycle in 2008 and is no longer available.

11 Installation For optional connectors, contact your Danfoss representative. Wiring A barrier terminal strip inside the handle s case provides connections to power, ground, and potentiometers when no external cable is ordered. Run a cable from the strip through the strain relief provided on the side or bottom of the case. Reference Potentiometer option on page 14. A clockwise handle movement causes a current flow from terminal B to A when the terminal strip is facing you. W Warning An unforeseen failure may cause an output which could activate a valve or pump. Unexpected vehicle or mechanism movement can endanger people or damage equipment. Handles equipped with a center-off switch will mitigate this condition. When an active neutral is necessary, provide an operator-presence interlock and/or braking system sufficient to stop and hold the system or vehicle. In most applications, auxiliary switches must be customer-wired, as shown in Potentiometer option on page 14. When the switch is used as a center-off, power is connected from the external 12 Volt supply to the terminal labeled common. The switch terminals are 3/16 inch quick-connect. PWM Option (primarily) on page 15 shows a pre-wired control handle with center-off switch and Delphi connector, exhibiting the handle phasing and color coding of the wires. The following illustration shows how to assemble the mating Delphi connector (male shell, female sockets) used in PWM Option (primarily) on page 15.
